MEANS FOR ADJUSTING AND STRETCHING CARD-CLOTHING.

SPECIFICATION forming part of Letters Patent No. 455,672, dated July 7,1891.

Application filed December 26, 1390- Serial No. 375,849. (No model.)

To all whom it may concern.-

Be it known that 1, WILLIAM ILTORREY, a citizen of the United States,residing atAdams, in the county of Berkshire and State of Massachusetts,have invented certain newand useful Improvements in Means of Adjustingand Stretching Card-Clothing, of which the following is a specification.

My invention relates to improvements in means to be applied to thetightening-bar of carding-cylinders for adjusting and stretch ingcard-clothing upon the said cylinders.

My invention further relates to the tightening-bar employed to span thecard-cylinder from arch to arch between the pins after the removal ofthe flats and to be wedged and screwed so as to bring the arches tightlyagainst the card-cylinder, making the latter immovable while thecard-clothin g is adjusted and fastened.

The object of my invention is to facilitate the operation of stretching,adjusting, and fastening the card-clothing upon the card-cylinder.

I'Vith these ends in view the invention consists in the novelconstruction and arrangement of the several parts, as will behereinafter more particularly described, and specifically pointed out inthe claims.

I have fully and clearly illustrated my in Vention in the accompanyingdrawings, in which- Figure 1 is a view of a card-cylinderclothingmachine to which my invention is applied. Fig. 2 is a detail perspectiveof the invention. Fig. 3 is a view of the tighteningbar removed from themachine.

Similar letters of reference indicate corresponding parts in the severalfigures.

In the drawings, A is atightening-bar, which may be of any size orshape, said bar being applied to a cardinr-cylinder so as to span thesame from arch to arch after the removal of the top-flats, and thenwedged and screwed so as to bring the arches tightly against the ends ofthe card-cylinder, holding the same rigidly in position while thecard-clothing is adjusted and fastened. An adjusting-screw is employedto bring the arches together against the card-cylinder.

My device for stretching, adjusting, and

fastening the card-clothing upon the card-cylinder is used upon thetightening-bar by adjusting the hinged shaft-box on the bar andfastening the same with thumb-screws.

A is a hinged shaft-box having a hinged side or bottom G, pin-fasteningH, and set-- screws F to hold the box steadily upon either a round orsquare shaft. Through this boX passes a worm or screw B and guide-bar 0,both the worm B and guide-bar 0 being attached to'the swivel D, the Wormor screw by nut K, which has an opposite screw-t-h read to that of theworm or screw B, and the guidebar is secured permanently in anysuit-able manner or formed integrally with the swivel D. The worm orscrew is operated by means of a wheel or ratchet motion. The clamps Iare attached to the card-clothing as ordinarily used and connected withthe swivel D of the stretcher or adjuster by means of a strap.

By means of the hinged box A themachine is rendered readily adjustablerelative to the tightening-bar of the card-cylinder and is operated atany angle desired, the set-screw F holding the shaft-box in positionupon either a round or square shaft. The guide-bar G gives additionalstrength and firmness to the device and serves to hold the swivel D in afixed position.

By the construction of my device it can be used on a tightening-barwithout removing the doffer-roll, and from the opposite side or end ofthe card-cylinder by simply removing a few top-flats, thus making theoperation of clothing the card-cylinder or adjusting thecard-clothingthereon very simple, resulting in a great saving of timeand labor over the old construction. The card-clothing by this devicecan be' drawn or stretched to the fraciional part of an inch, asdesired, and retain its position until released.

From the foregoing description, taken in connection with theaccompanying drawings,

the operation of my device will be obvious.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. The combination, with the tightening-bar of a card-clothing machine,of an adjustable sleeve adapted to be clamped to the bar and formed witha threaded aperture and vertically-projecting guide-lugs, a threaded barthrough the threaded aperture of the sleeve, a swivel on the end of thethreaded bar, provided with a guide-rod arranged in the guidelugs of thesleeve, and. means, substantially as described, for turning the threadedrod.

2. The combination, with the tighteningrod of a card-clothing machine,of an adjustable sleeve provided with a hinged side or bottom adapted toclamp the sleeve on the rod, said sleeve being provided with a threadedaperture and vertically-projecting guide-111 gs,

a threaded rod arranged in the aperture of [5 the sleeve, a swivel onthe end of the threaded bar, arod connected to the swivel and adapted totravel between the guide-lugs of the sleeve,

and means for turning the threaded rod, substantiallyas described, andfor the purpose 2o specified.

In witness whereof I hereunto set my hand in the presence of twowitnesses.

WILLIAM H. TORREY.
